NAME
systemd-networkd-wait-online.service, systemd-networkd-wait-online -
Wait for network to come online
SYNOPSIS
systemd-networkd-wait-online.service
/lib/systemd/systemd-networkd-wait-online
DESCRIPTION
systemd-networkd-wait-online is a oneshot system service (see
systemd.service(5)), that waits for the network to be configured. By
default, it will wait for all links it is aware of and which are
managed by systemd-networkd.service(8) to be fully configured or
failed, and for at least one link to be online. Here, online means that
the link's operational state is equal or higher than "degraded". The
threshold can be configured by --operational-state= option.
OPTIONS
The following options are understood:
-i INTERFACE[:MIN_OPERSTATE[:MAX_OPERSTATE]],
--interface=INTERFACE[:MIN_OPERSTATE[:MAX_OPERSTATE]]
Network interface to wait for before deciding if the system is
online. This is useful when a system has several interfaces which
will be configured, but a particular one is necessary to access
some network resources. When used, all other interfaces are
ignored. This option may be used more than once to wait for
multiple network interfaces. When this option is specified multiple
times, then systemd-networkd-wait-online waits for all specified
interfaces to be online. Optionally, required minimum and maximum
operational states can be specified after a colon ":". Please see
networkctl(1) for possible operational states. If the operational
state is not specified here, then the value from RequiredForOnline=
in the corresponding .network file is used if present, and
"degraded" otherwise.
--ignore=INTERFACE
Network interfaces to be ignored when deciding if the system is
online. By default, only the loopback interface is ignored. This
option may be used more than once to ignore multiple network
interfaces.
-o MIN_OPERSTATE[:MAX_OPERSTATE],
--operational-state=MIN_OPERSTATE[:MAX_OPERSTATE]
Takes a minimum operational state and an optional maximum
operational state. Please see networkctl(1) for possible
operational states. If set, the specified value overrides
RequiredForOnline= settings in .network files. But this does not
override operational states specified in --interface= option.
--any
Even if several interfaces are in configuring state,
systemd-networkd-wait-online exits with success when at least one
interface becomes online. When this option is specified with
--interface=, then systemd-networkd-wait-online waits for one of
the specified interfaces to be online. This option is useful when
some interfaces may not have carrier on boot.
--timeout=SECS
Fail the service if the network is not online by the time the
timeout elapses. A timeout of 0 disables the timeout. Defaults to
120 seconds.
-q, --quiet
Suppress log messages.
-h, --help
Print a short help text and exit.
--version
Print a short version string and exit.
